Effect of Current Distortion and Unbalanced Loads on Semiconductors Reliability [PDF]
IEEE Access, 2021 This article presents a reliability analysis of a 4-wire grid-tied inverter under different loading conditions, considering unbalanced loads and harmonic distortion in the current consumed. The proposed power converter is used as a case study to assess the impact of current disturbances on the semiconductors’ reliability.
